One of the practical op-amp limitations is the rate at which the output voltage can change. The limiting rate of change for a device is called its "slew rate". The slew rate for the 741 is 0.5V/microsecond compared to 100V/microsecond for a high-speed op-amp. The LH0063C has a slew rate of 6000V/microsecond. The slew-rate imposes high-frequency limitations on the device. At some critical frequency, an output swing equal to the supply voltages will require a slew rate faster than the maximum slew rate of the device. Above that frequency, the amplitude of distortion-free output voltage swing will be limited.
The slew rate is inherently limited by the small internal drive currents of an op-amp but is also limited by internal capacitance designed to compensateagainst high frequency oscillations. Some op-amps are externally compensated and therefore offer some control over the slew rate.
The slew rate for a given amplitude V and frequency f is

Rate of change of charge with time. its called current.
Q=K Squareroot of (DP/SG) Q=Flow rate DP = Pressure diffrence (P1-P2) SG= Specific gravity
The same as the acceleration rate. Measure the speed at one moment of time, measure the speed at another moment of time, calculate the difference, divide by the time elapsed.
These are all variables used to calculate evaporation rate: The larger the surface area the higher the evaporation (rate) The higher the wind speed the higher the evaporation (rate) The higher the temperature the higher the evaporation (rate) The higher the relative humidity the lower the evaporation (rate)
A: The application is for DAC ADC converters where the fastest slew rate is desirable for fast conversion
the slew rate of an op-amp represents the maximum rate at which the output can change , no matter how large an input signal is applied the slew rate of an op-amp is specified in V/s or V/mew second.
slew rate is the ability of an amplifier to reproduce amplified version of the input signal in terms of frequency and phase. The input signal amplitude change is fast. But the amplifier will take some time to give response to the changes in input signal. i.e. how fast the amplifier tracks the input signal is the slew rate. For an amplifier the slew rate should be high in order to avoid signal distortion. The rate of change of the output voltage of an amplifier for the given input signal change is called the slew rate.
0.5V/us
slew rate is caused by current limiting and the saturation of internal stages of an op-amp when a high-frequency,large amplitude signal is applied.
you cannot ever achieve that . the 741 has inherited storage time due to overdrive and the slew rate is not exactly fast. it can be done provided by tweaking the input drive and selecting amplifiers
as it is rate of change of output voltage..so it affect amplifier output
IC741 has a low slew rate because of the predominance of capacitance present in the circuit at higher frequencies. As frequency increases the output gets distorted due to limited slew rate.
1 x 741 = 741 3 x 247 = 741 13 x 57 = 741 19 x 39 = 741
225% of 741 = 225% * 741 = 2.25 * 741 = 1,667.25
